<p>PCT No. PCT/DE95/01081 Sec. 371 Date Jul. 25, 1996 Sec. 102(e) Date Jul. 25, 1996 PCT Filed Aug. 17, 1995 PCT Pub. No. WO96/05525 PCT Pub. Date Feb. 22, 1996The invention relates to a method of manufacturing prisms, particularly microprisms and beam-splitting prisms, including the following steps: a) producing rectangular plates (1), b) fixing a larger number of these plates at their plate surfaces (2) to form a rectangular block (4), c) processing at least one face (support face 5) of the block at a right angle relative to the plate surfaces, d) rearranging the plates of the blocks so that all plate surfaces are aligned at an angle alpha 1 and that the sharp edges of the plates are placed in contact with the alignment plate (6), e) cementing of several displaced blocks with their cover faces (11) to a carrier body and grinding and polishing the support face (5), f) multiple repetition, if necessary, of steps d) through e) with different angles adjustments alpha , g) rearranging the plates of the blocks so that all plate surfaces are arranged at an angle beta , h) cementing an auxiliary plate (16) to the optically effective surfaces (8, 12), i) cutting off prism strips (18) at a distance a from the surface of the auxiliary plate (16), j) cutting off the microprisms (10), k) detaching the microprisms from the auxiliary plate (16). Very different shapes of microprisms can be produced (FIG. 5).</p> |
